Parallel Expanding Gate Valve This unidirectional expanding gate valve gives an extraordinarily high mechanical seating seal force that acts simultaneously against both seats. The seating force is not affected by line pressure fluctuations or vibrations.
Some parallel gate valves are designed to allow the seat to be springenergized by an elastomer that applies constant pressure to the disk gate seating surface. In the doubledisk parallelseat type, the valve is closed by lowering the disks from the valve neck to a height equal to that of the valve seats.
A typical through conduit gate valve, slab type, WCB body, bevel gear operated. The through conduit gate valve is a typical parallel gate valve. Metals Valve supplies through conduit gate valves in two series slab gate and expanding gate.
The parallel gate valves use a flat gate between two parallel seats, and a popular type is the knife gate valve designed with a sharp edge on the bottom of the gate. The wedgeshaped gate valves use two inclined seats and a slightly mismatched inclined gate.
Parallel Gate Valve. Size Cast Steel Through conduit Gate Valves have been designed to meet the requirements of API 6A; Face to Face and End to End dimensions conform to API 6A; End flange dimensions conform to API 6A; Butt weld end dimensions conform to API 6A;
All gate valves are not created equal, and there are several different technologies to consider when choosing a gate valve for a specific application including wedge gate, slab gate, conduit gate, expanding compact gate, parallel slide gate, and single disc.
The parallel gate valves are slide valves with a parallelfaced gatelike closure member including knife gate valve series and through conduit gate valve series. The closure member can be ether single disc or double discs, soft seated or metal seated.
Parallel slide gate valve with equalizer Babcock valves also design and manufactures parallel slide gate valves, that avoid any flow turbulence, and minimize the pressure drop. The parallel slide gate valves are an alternative option of double disc valves, having single wedge instead of double wedge. The horizontal spring keeps the discs in
Parallel Expanding Gate valve. This valve has a split gate with parallel sealing faces, inclined internal surfaces, and parallel seats. The two gate halves are forced out against the seats at point of closure, providing a tight seal without the assistance of fluid pressure. Seats may be fixed or floating.
Parallel gate valves are slide valves with a parallelfaced gatelike closure member. This closure member may consist of a single disc or twin discs with a spreading mechanism in between. Typical valves of this type are shown in Figure 325 through Figure 332. Figure 325 Parallel Slide Gate Valve
Parallel Slide Gate Valves Operation Pentair reserves the right to change the contents without notice page 3 Valve Operation When a Parallel Slide is opened or closed, the positioning of two flat spring loaded discs will either

Dewrance Style A Wedge Gate and Parallel Slide. General Application Our pressure seal Style A gate valves are recommended for several applications in the power industry, in particular in feed water lines, steam lines, and in services which involve high temperatures media.
Parallel Slide Bolted Bonnet This type of onoff valve is an alternative to the traditional wedge type gate valves. The disc is in two halves, spring loaded, that seat on parallel
FLUITEK ORSENIGO VALVES has very extended experience in manufacturing this type of valve. They are an alternative to the traditional flex wedge type gate valves. The disc is in two halves, spring loaded, that seat on parallel seat rings.
Parallel Gate Valves Parallel Slide Gate Valves For those applications when large temperature variations are expected or fast shutoff is required, this is the most ideal design. The seats are parallel and the disc has no contact with the seats during the stroke of the valve.
Hopkinsons174; Full Bore amp; Venturi Parallel Slide Gate Contact us for more information We recommend Hopkinsons 174; Full Bore amp; Venturi valves when a gate valve is required for steam or feedwater duty in medium and high pressure ranges.
The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream. Shutoff is obtained by the freefloating seat or disk gate allow the upstream pressure to seal the seat and disk against any unwanted seat leakage.
Expanding Gate Valve 4 MJ1761 Issued March 2006 The Mamp;J Model EG valves are full bore through conduit valves with rising stem and parallel expanding
One of the most comprehensive valve product lines available from any manufacturer. From the most common application to the most severe, Velan has a solution.
GWC produces a full line of API6D Through Conduit Gate valves in both slab and expanding gate design.
Like the doubledisc or parallelseated gate valve, its disc seats against the downstream seat, depending on the flow direction. The inside diameter of a conduit gate valve is equal to the inside diameter of the connecting pipe.
